When I worked at a small startup, we were moving to a new office and I was asked to help with the buildout. I engaged with the flooring vendor, and he came by one day to drop off a carpet sample. He put it on my desk where my mouse was. It was a rectangle sample of tight knit office carpet, about 18”x22”. When I got back to my desk, I just put my mouse on top of it and started using it as a mouse pad. That was 15 years and 3 companies ago, and I still use it as my mousepad. It’s perfect for the mouse to glide on, soft enough for my wrist to rest on, absorbent of sweat or drink condensation, and large enough I never hit the edge. I will never not use it. It is my mouse carpet, and I love it.
